7 4 Claims. 1 This invention relates to a driving mechanism and, more particularly to a driving mechanism including a prime mover having its output del v e a l ad i An object of thisinvention is to provide a power unit for delivering power from a prime mover to a rotating body wherein part of the weight of the prime mover and the driving mechanism i utilized in applying a friction drive to the rotating body.

Another object of this invention is to provide an, 'electridmotor or a gas engine drive for a grindstone or the like, wherein a pulley or wheel is used in driving thegrindstone by direct engagement therewith, which pulley or wheel also functions as a surfacing tool for the grindstone. )Another object of this invention is to provide a, drive for a device wherein the drive is easily applied, easily adjusted and at the same time dependable and efficient. t l j Another, object of this invention is to provide an electric motor drive to be used in driving varioustypes of equipment, as for example, a pump, a churn, a fanning mill for cleaning seed a washing machine, a cream separator, a bicycle, apower hack saw and numerous other devices.

jQther objects and advantages reside in the construction of parts, the combination thereof and. the mode of operation, as willbecome moreapparent from the following description; Inthe drawings,"

plate 48 in any suitable manner.

I the grindstone l0.

Referringto the drawings, the reference character It) indicates the conventional grindstone mounted upon an arbor shaft l2 mounted in the bearings I4. The bearings M are mounted upon the frame members It which may consist of a pair of. angleirons supported upon legs [8. The legs 18 may be braced by suitable cross rods 20. A pair of longitudinally extending frame meme bers 22 supported upon the legs l8 have mounted thereon a trough 24 for supplying water to the grindstone I0. ,Aside from the fact that the framemember it extends beyond the legs 18 on one end, the grindstone assembly described thus far has been shown as illustrative of conventional grindstone assemblies. The details of this assembly have merely'been shown for the purpose of illustration and may constitute conventional grinding wheels or grinding stones used on the average farm. I The grindstone assembly shown herein has been provided with a driving unit. This driving unit includes a supporting channel member 30', provided with laterally disposed parallel flanges 32 Iformingextensions 34 pivotally mounted at 36 to, the extensions ofthe frame members "I6. The channel member 30 has mounted thereon a motor-supporting bracket assembly including a' vertically disposed plate member 40 secured to the channel membertfl by a pair of bolts 42 mounted in selected pairs of holes i i shown in Figure 4. ,The upper end of the plate member 40 supports a hinge 46 joining to the plate 40 a, horizontally disposed plate 48 having one end secured to the channel member 30 by screws 50, A motor 52 is adjustably mounted upon the This motor 52. has, mounted thereon a V-belt pulley 54 driving a v-belt 56 passing over a V'-belt pulley 58 se cured to an arbor shaft 60 journalled in bearings 62 mounted upon an'extension 64 of the channel member 30 The shaft 60 has keyed thereto a drive pulley or wheel 66, resting on top of the grinder wheel [0. When the motor 52, is started, it drives the ,V-belt, 56, which in turn drives the shaft til and with it the wheel 66, frictionally driving the grindstone Ill. The weight of the parts supported upon the channelmember 30 and part of the weight of the channel member 30 are used in' applying apressure between the wheel 96 and This wheel fidwhich may be made from cast iron or steel'or any other suit able material, in addition to driving the grind; stone ill, functions as a surfacing wheel for surfacing the grindstone. It has been found 3 that even though the contour of the grindstone may be rough and irregular, the wheel 66 will gradually eliminate the irregularities, resulting in a grindstone provided with a uniform grinding surface.

In order to alter the effectiveness of the pressure exerted between the wheel 66 and the grindstone I0, the relative position of contact between the grindstone I and the wheel 66 may be adjusted by changing the position of the pivot 36 to one of the other holes I0 in the frame member I6. In so doing, the angle of inclination of member 30 i adjusted. When this is adjusted, the plate 48 slopes, so as to provide a sloping support for the motor 52. For some types of motors it is quite desirable that the motor be mounted on a horizontally disposed support, so that the bearings may be properly lubricated. Upon the angle of inclination of the channel member 30 being adjusted, the horizontal plate 48 may be adjusted by loosening the bolts 42 and changing these to some other hole 44 in the member 30, to thereby level the plate 48. By this arrangement it may readily be seen that the relative position of the wheel 66 may be adjusted with respect to the grindstone I0 and the horizontal support for the motor adjusted so as to remain in a horizontal position.

In the modification disclosed in Figure '7 a similar power unit has been used applied to a pump jack. The pump I00 may be any conventional pump provided with a pump rod I02 that may be urged upwardly by a spring I04,

so as to aid the pull, to thereby result in a smoother operating pump. As is well known to those skilled in the art, instead of a pump being actuated by hand, it maybe driven from any suitable source of power through a. pump jack including the vertical rods I06 and I08, the rods having their upperends connected to a cross bar I I0 connected to the pump rod by a U clamp H2. The lower end of the rod I06 is mounted upon a pintle or crank pin II4 fixed to a rotatably mounted'disc IIG keyed to a shaft H8. The shaft IE8 is journalled in a frame member I20 and terminates in a crank arm I22 provided with a crank pin I24 actuating the rod I08. The frame I20 is clamped in any suitable manner to the body of the pump'l0 0. The shaft I'I8' supports a drive wheel or pulley I30 that may be lined with suitable lining material, as for example, rubber, leather or a composition material. This wheel I30 is actuated by an internal combustion engine I40, which engine will not be described in detail, as any suitable engine now appearing on the market may be used.

The internal combustion engine I40 is mounted upon the ledge 48, identical to the ledge described in the preferred embodiment, mounted upon the upright membr I42 fixedly secured to the drive wheel 66 resting upon the drive Wheel I30, so as to transmit motion thereto. The low-er end of the bars 30 are pivotally attached to the U-shaped frame member I50 having one end supported upon the support I52 and the other end I54 connected in any suitable manner to the base of the pump I00. I Instead of the motor being mounted for supplying power, the engine I40 drives a V-pulley I60 driving a V-belt I62 actuated by a suitable pulley I64 driving the'shaft I42. Instead of using a gas engine, an electric motor can be used for supplying power to the pump.

-Various other modifications may be provided within the purview of this-invention.

Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
